Web Services ?

So - how does one interface 100+ domino lotusscript classes to a portal front end ? Paul R and myself are coming to the conclusion that the lotusscript classes have to be web-service-enabled, and the portal itself provide just a thin veneer of user interface..

Any thoughts on this ? Can Java call Lotusscsript classes ? (Lotusscsript can call Java classes).

Oh - and anyone got serious experience putting websphere, portal, and existing domino and sametime installations onto the same wintel box, allowing both domino http and websphere portal web sites (with seperate IP addresses) work ? Any pointers ?
